Forged Steel Valve
Forged steel lift check valve overview
The h61y forged steel lift check valve is available in three bonnet designs. The first type is a bolt-type bonnet. The valve is designed according to this design. The valve body and the bonnet are connected by bolts and nuts, and the wound gasket (made of 316 clamp flexible graphite) is sealed. Metal rings can also be used when customers have special requirements. The second design form is a welded bonnet. According to this design, the valve body and the bonnet are screwed and fully welded. Full penetration connections are also available when the customer has special requirements. The third type is a pressure self-tightening valve cover. The valve designed according to this design form has a valve body and a valve cover which are screwed, and an internal pressure is sealed from the sealing ring. There are three different designs for check valves: lift check valves, ball check valves and swing check valves. Forged steel lift check valve design structure and characteristics h61y forged steel lift check valve is designed and manufactured in accordance with mssp-118 and asme b16.34. Test and test by api 598, mark by mss-sp-25.
